LOCKING DEVICE FOR :FUEL-SUPPLY VALVES.

Specification of Letters Patent.

application med November 14, 1912. serial No. 731,278.

To all whom t may concern.' 1

Be it known t-hat I, ALBERT K. HARNLY, a citizen of the United States, residing at Reading, in the county of Berks and Sta-te of Pennsylvania, have invented'certain new and useful Improvements in Locking Devices for Fuel-Supply Yalves, of which the :following is a specicationf My invention rela-tes tovimprovements in locking devices for fuel supply valves, and it` is particularlyk applicable to motor vehicles in which a liquid fuel is used.

My invention comprises a iexible connection between' the fuel control valve and a locking device located on the dash board iinmediately before the driver, so that the fuel valve may be opened or closed through the locking device, even though the valve is not in alinement with the locking means.

Another feature of my invention is the locking device, the'particular construction of y which permits the .operation of the valve through the medium of the above noted flexible connection.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawings, in Whichz-v f F igureA 1 is side elevation of the forward part of a vehicle with my invention applied thereto. HFig. 2, is an elevation of a section of the .dash board, showing lthe location of the locking device and the flexible connection to the supply valve. Fig. 3 is a central section of they locking device... Fig. 4 is a 'detail showing the flexible connection attachment to the fuel supply valve. Fig. 5 is a viewsimilar to Fig. 3, but with the locking device shown in side elevation. Fig. A6 is a section on line 6-6 of Fig. 3. Fig. k7,is a section on line 7-7 of Fig. 3.

The 'numeral 1 designates the forward end of the body and 2 the dashboard of an ordinary vehicle. The numeral 3 designates the fuel supply pipe, leading from a source of supply to the carbureter, and 4 designates the .fuel supply valve located'in said pipe,

and which in the present construction may be located at any convenient point and must not necessarily be loca-ted immediately below and in vertical alinement with t-he dash board. y

`The numeral 5 designates a flexible tubular connection, formed of a tightly coiled wire, and attached to the valve stem 6 at one end, While its other end is attached in tlike Ina-nner to the stem 7 of the locking means 8. This attachment is made by means of a sleeve 9 attached to the respective stems and set screws l0 for holding the sleeves to the stems so that the stems, sleeves and flexible member will turn together, lthe flexible member being forced over the end of the sleeve `which is formed with aseries of annular grooves 11 to accommodate three: or four convolutions of the coil.

suitable key barrel 12which carries a projecting pin 13 and this pin moves in a slot 14 being located. away fromy the axial center of the body 8, the endof t-he pin describes an arc that brings it beyond thesurfaoe of the body when it reaches the center of its travel. The lock S is provided with a set of pin tumblers l5, to be Vactuated by a key 16, which will permit the barrel to be turned. The sleeve 17 is formed with an internal groove 17a to engage the locking pin 13.

The body 8 of the lock passes through the sleeve 17, located in an opening in the dash board and formed with a flange 18 which is vattached to the inner face of the dash board by bolts 19. The inner face of the ange is dished at 20 to permit the enlarged inner end of the body 8 to seat therein, and, while the dished portion is 'annular `in form, the bottom thereof is rect-angular, as shown by tangular shank 22 on the body 8.

When it isdesired to close the fuel suped in the lock and the turning of the barrel 12 will carry the pin 13 to either side of the center,- where its end lies within the outer body fromv the sleeve 17 and permitting the Fig.` 5, which movement is limited by the lhave thus been drawn forward, the shank 22 tangular seat 21 in the sleeve 17, and this release will permit therbody 8 to be turned valve will permit vthis turning even though horizontal andvertical alinement with the locking device. To secure the valve in said closed'position, the body 8 is pushed back to Patented May 20, 1913.

when the barrel turns, so that, the barrel surface of the body 8, thus releasing thewasher 23 on the `stem 7.' When the partsI the valve is llocated at a point out of bot-h The body.8 of the ylock is provided with a L numeral 21 in Fig. 5, to accommodate a recv ply valve for any purpose, the key is insert- I longitudinal forward movement thereof, Y from the position shown in Fig. 3 to that of i has been released. from its square or recsufficiently to close the valve, and the exif ble connection bet-ween the lock and the lio its position in the sleeve until the squared portions meet :v the key is turned until the pin 13 is in vertical or locked position, and the` key is withdrawn.

Having thus described my invention, I claim l Y l. A locking device for fuel control valves comprising a sleeve formed with an internal annular groove, and a ange formed with a dished surface, a portion of which is rectangular in outline; a body portion formed with a rectangular shank for engagement with the dished portion of the sleeve; a key barrel; a pin carried by said barrel and adapted to travel in the groove in the sleeve -whereby the body is -lockedor unlocked with' relation to the sleeve; and ak key for turning said barrel.

the sleeve whereby the body is locked or unlocked with relation to the sleeve; an annularly grooved sleeve securedl to the stem of the body portion, and a flexible member secured in the grooves of said sleeve and adapted to rotate therewith.

3. In a locking device for fuel control valves, a sleeve formed with an internal annular groove, a ange, means for securing the flange' to a body, said flange having a dished face, a portion of which is rectangular in form; a4 body adapted to rotate in the sleeve and having an enlarged end formed with a rectangular shank for engagement with the dished surface in the flange; a key barrel in said body provided with a pm adapted for engagement with the internal groove in the sleeve to lock the body against movementwith relation to the sleeve, and key operated means for releasing said pin engagement.

In testimony whereot` I aitix my signature in presence of two witnesses.
